An 80's Miami term used to describe a kid (roughly age 12-
14) that thinks he's more grown up than he really is. The word is a Miamized translation of Spanish word "mojon" which
mean turd.
"I hate going to the

packed with mojohns that get in your
face and talk mad shit."
"Just because Yazmani is in 7th grade, he thinks he's hard, but he's a mojohn."
"I can't believe that mojohn had the balls to mack it to my girl."
